POWER ATTACHMENT FOR PUMPS.

Patented in... so, tart.

Application filed November 24, 1915. Serial No. 63,175.

either rigidly fixed to the pump-stand permanently or constitutes a jack which rests upon the floor adjacent thereto.

The primary object of my invention is to provide a power-attachment which may be readily attached to and detached from a pump-stand, the nature of the attaching devices enabling the stand to satisfactorily support the attachment while the apparatus is in use;

It is a further object of the invention to.

provide a device which will be satisfactory in light work.

It is a further object of my invention to provide a device which can be attached to a. pump-standin a most economical and con venient manner, simple in all its parts and at a low cost.

In the accompanying drawings, Figure 1 is a side elevation of the device; Fig. 2 is a rear elevation thereof; Fig. 3 is an enlarged side elevation with parts not shown; Fig. 4 is a rear elevation of the parts shown in Fig. 3; and Fig. 5 is a cross section on the line 55 of Fig. 3, looking in the direction of the arrows.

The drawings disclose one embodiment of the invention in which 1 indicates the pump stand. Cast integral with this pump stand or fixed to it in any suitable manner are two pairs of spaced lugs indicated at 2 and 3. These spaced lugs are adapted to be engaged by the attachment indicated generally at 4. This attachment 4 is here shown as a pair of bearings 5 and 6 spaced vertically above each other. It will be observed from the drawings that I have shown the lugs as attached to or carried by the pump stand, while the arms which interlock with the lugs are carried by the attachment, but it will be understood that any transposition of these parts will be within the scope of my invention. Journaled within these bearings are shafts 5 and 6'. The shaft 5' has fixed thereto at its ends a band wheel, as indicated at 7, and a gear 8. The shaft 6 has attached thereto at each end a gear wheel 9 adapted to mesh with the gear 8 and a crank wheel 10. The wheels 9 and 10 have thereon the well known wrist-pin and pitman which is adapted to be connected with the piston rod of the pump. As this structure is well known and forms no part of this invention it is not described in detail. I

The means for attaching the member 4 to the lugs will now be described. This means comprises a lower pair of arms 11 arranged to embrace the stand 1 and to engage the lower pair of lugs 2 by means of slots 12 therein. The member 4 also has a pair of arms 13 located at the upper part thereof and embracing the stand 1. These arms have hooks thereon, indicated at 14, for engagement with the upper lugs.

The numeral 15 indicates a screw-threaded aperture in which operates a set screw 15.

From the above description it will be seen that I have invented a device that is simple in all of its parts and which is easily attached. It should be noticed that the slot 12 in the arm 11 prevents the member 4 from working downward and back and forth. The upper member 13 is simply hooked around its lug and has a certain amount of play. The set screw, however, will rigidly fix the device to the standard and prevent all play. When the power drive is in operation the thrust is downward and this insures the location of the member 4 securely upon the lugs, the set screw holdingthe same rigid.

From the oregoing disclosures it will be further observed that in the manufacture and marketing of this invention it may leave the factory as a complete whole, the pump stand and the power attachment constituting such complete whole, or that the pump stand may be manufactured and sold as a part of the pumpwithout the inclusion of the power attachment which the urchas'er at some later or other time may uy and use by attaching it to his stand. Therefore, in the practical marketing of the invention it will happen that some shipments will be made of the complete whole, the

' Letters Patent, is

' wardly therefrom,

pump stand and the power attachment, while in other instances, these parts will be sold and shipped at different times.-

\ While I have shown and described one embodiment of my invention it will be understood that this has been chosen for the purposes of illustration only, and that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by 1. The combination, with a pump stand provided with fixed lugs projecting outwardly on opposite sides thereof, of a power attachment provided with arms embracing said stand and having portions hooked over said lugs.

2. The combination, with a pump stand provided with fixed lugs projecting outarms embracing the stand with the slots engaging the lugs, whereby the attachment is supported from the stand and movement back and forth is prevented.

5. The combination, with a pump stand provided with ,fixed lugs pro ecting outof a power attachment provided with a slotted member engaging certain of the lugs, a pair of-hooked arms embracing said stand-and hookedover other of said lugs, and clamping means.

6. In a power attachment for pumps, 0. pump stand having lugs thereon arranged in pairs, a member adapted to support power mechanism having arms thereon arranged in pairs, each pair of arms embracing the said pump stand and engaging a pair of In s.

In a power attachment for pumps, a member adapted to support power mechanism, said member comprising hooks adapted to en age a pump stand, one of said hooks belng slotted to prevent movement downward and back and forth,'the other of said hooks arranged to allow play, and a device on said member adapted to lock said memberrigidly to said pump stand.

8. In a power attachment for pumps, a pump stand having spaced lugs thereon, a member adapted to support power mechanism, spaced arms-on said member, one of said arms being slotted and in engagement with one of said lugs, the other of said arms vhavin a hook in engagementwith the other of sai lugs, and a set screw to render the engagement rigid.

In a power attachment for pumps, a pump stand having lugs thereon arranged in pairs, a member adapted to support power mechanism having arms thereon arranged in pairs, each pair of arms embracing thesaid pump stand and engaging a pair of lugs,

and means to render the engagement rigid.

10. In a ower attachment for pumps, a pump stan having pairs of lugs spaced vertically, a member adapted to support power mechanism having pairs of arms arranged vertically thereon, the lower, pan of arms embracing the said pump stand. and detachably engaging the lower pair of lugs,

the upper pair of arms embracing the pump stand and detachably engaging the upper .pair of lugs, and means to render the engagement rigid.

In testimony whereof, I aflix my signature.

PHILIP A. MYERS.
